Provide a property to customize the application path that serves as the
base URI for a JAX-RS compliant application. If both `spring.jersey.path`
and an `@ApplicationPath` are present, the property takes precedence.

Update WebMvcAutoConfiguration to use a RequestContextFilter instead of
a RequestContextListener.

Using a filter is required for some Spring Session operations (see
https://github.com/spring-projects/spring-session/issues/129).

This update also has the added benefit of allowing the Response to be
accessed from RequestContextHolder.getRequestAttributes() by casting it
to ServletRequestAttributes.

Logback documentation explains how to initialize the logging system and
namely how the `logback.configurationFile` system property can be used to
specify the configuration file to use.

Spring Boot has an abstraction on top of that. A user can define the
`logging.path` property regardless of the logging infrastructure it is
using.

Users following the logback documentation can be confused at first so
we're not logging a warning when we found out that the logback specific
property has been specified.

Previously, the launch script would always use a file named
<appname>.log to capture the application's console output. This commit
adds a variable, LOG_FILENAME, for specifying the file name defaulting
to <appname>.log.

Previously, HornetQ and Artemis tests were using a test configuration
class listing the configuration classes to use explicitly in the purpose
of disabling the XA support.

This had a very unfortunate side effect for Artemis as we forgot to add
an import on the "real" configuration and this got unnoticed because of
this duplication.

It turns out that this special configuration class is no longer necessary
as XA backs off automatically anyway now. The tests have been updated
to use the regular auto-configuration and were failing with Artemis. The
import has now be added.

Commit adf2c44b was an attempt to prevent HSQLDB from throwing an
exception when the JVM exits. This was achieved by disabling the
application context’s shutdown hook in the tests. This had the unwanted
side effect of causing tests’ application contexts not to be closed. The
reported symptom was that @Destroy methods were no longer being invoked.
We need a different solution to the problem.

The exception was:

Caused by: org.hsqldb.HsqlException: Database lock acquisition failure: attempt to connect while db opening /closing
    at org.hsqldb.error.Error.error(Unknown Source)
    at org.hsqldb.error.Error.error(Unknown Source)
    at org.hsqldb.error.Error.error(Unknown Source)
    at org.hsqldb.DatabaseManager.getDatabase(Unknown Source)
    at org.hsqldb.DatabaseManager.newSession(Unknown Source)
    ... 23 common frames omitted

I originally thought this was due to a race between the application
context’s shutdown hook and HSQLDB’s shutdown hook, however HSQLDB
doesn’t use a shutdown hook. I believe that the problem is due to 
an HSQLDB database being created with shutdown=true in its URL, similar
to the problem described here [1]. This will shut down the database when
the last connection to it is closed, however the shutdown will happen
asynchronously. If the JVM then runs the application context’s shutdown
hook, EmbeddedDatabaseFactory will attempt to connect to the database to
execute the SHUTDOWN command. This executes synchronously but will race
with the asynchronous shutdown that’s executing as a result of
shutdown=true in the JDBC url and the last connection to the database
being closed. 

This commit reinstates the use of application context shutdown hooks in
the tests, and updates the documentation to recommend that, if a user
manually configures the URL for their embedded database, they do so 
in such a way that the database doesn’t shutdown automatically, thereby
allowing the shutdown to be driven by application context close.
